U TED Specification forming partof Letters Patent No. 11S, (lat September 24, 1879.

Be it known that we, JosEPH MO RE and GEORGE W. DlCKIE, of San Francisco, State of California, have invented an Improved "Method of Operating Pumps in Mines; and @we do herebydeclare that the following isa full, clear, and exact descriptiouthereof, reference being had to the drawings accompanying this specification, and forminga part of the same.

Our invention relates to a novelarrau gement for supplying power from a centralstation to v a number of contiguous mines; and it consists inthe employment of hydraulic pressure generated by asteam'or water operated pump or pumps, and one or more pressure accumulators, and transmitted through pipes to the dif-' ferent mines, where it is used for operating the pumps, hoisting, blowing, and for other purposes, and then returned through'otlier pipesto a water-tank, from which it is again pumped into the accumulator tobe-used over again.

\It also relates to a novel arrangement for operating pumps by hydraulic'pressure, all as hereinafter more fully described, and shown in the annexed drawings, in whichFigure l is a j a perspective, and Fig. 2 a detail view.

In order to operate the pumps at thelmines we secure a strong bracket, 1), to the ordinary spear or pump-rods Q, such as are now used.

"We then locate a ram or upright cylinder, R, o under each bracket, so that the piston-rod of i the cylinder will strike the under sideyof the,

bracket,and lift the pump-rod when the piston rises. We theu connect the branch pipe.

m with the cylinder below the piston, and also lead a waste-pipe, s,'from the cylinder tothe water-tank H at the central station, from which the water is pumped into the accumulator. A valve, u, is arranged in the length of the branch pipe near the cylinder, and another, 1),,

in the waste-pipe 5 and these valves are operated by the motion of the pump-rods so as to open and close alternately, thus admitting the water to, and discharging it from, the cylin ders. This'causes the pump-rod to be noved up and down by the motion of the piston act ingou the bracket 1). a

By the above-described means an entire mining district, when the mines are couveniently situated, can be supplied with a cheaper and more reliable .power-than when separate engines are used, and the mines will at iall times have command of a larger surplus of power, because two or more engines can be maintained at the central station, each of which 1 is sufficient for ordinary work, so that in case p one shouldbecome disabled the other could ed December 9, 1879; application filed .EOllhBI suitableandconvenient power. 13 is the boiler which supplies steam for operating the engine. y l

be used. By this arrangement, should any of the mines strike a body of water suddenly,

then at once the surplus power can be drawn i l to that particular mine to operate upon the surplus water. Should the power still be 'inadequate it would take but a short time to add another pump to pump into the same-accumu The ram or cylinder I of the accumulator'we 3 i connect by a pipe, 70, with a main pipe, L, which leads to the various mines to be supplied with l power, and this pipe we tap opposite each mine lator, and thus furnish all the power required Should it 'befound necessary to add more cylinder-power to operate the spear-rods, another bracket can be by the drowned mine.

bolted to the rod and another pi'essurecylinderadded, as in the first case, or, if deemed advisable, a water engine and pump can be placed in the mine under ground, and the water forced from the bottom direct to the surface, as at present done by the air-driven pumps.

By a proper regulation of the valves u c, the stroke of the pump-rods can be governed so as to give a quick upstroke and a slow downstroke, thus giving the water time to get out of the way of the descending pistons, which is averyimportant consideration in the working of 1nining-pumps.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. The improved system of supplying power to mines, consisting in forcing water into an accumulator, I J, by means of one or more pumps, D, at a central station, and then conducting the water through a main pipe, L, and

branch pipes m to' the mines, and after its pressure has been utilized leading the water back through waste-pipes s to a tank, T, to be used over again, substantially as specified.

2. The water cylinders or rams, R, connected with a hydrzuilic-pressure apparatus, I J, by pipes L m, and provided with the waste-pipes s, and having the alternately-operated valves u n, in combination with the pump-rod Q, with its bracket 11, substantially as and for the purpose above described.

In witness whereof we have hereunto set our hands and seals.
